The Duramax LLY 6600 is a high-performance diesel engine first introduced in 2004. Understanding the specifications for this engine allows you to know whether it might fit into your engine rebuild project, and whether it has sufficient horsepower and performance to suit your needs.
Engine Type
The Duramax LLY 6600 is a diesel forced-induction engine that operates via turbocharger. This forces additional air into the engine, allowing for more robust combustion and a higher power output.
Performance
The Duramax LLY 6600 produces a total of 310 horsepower at 3000 rpm and 565 ft.-lbs. of torque at just 1600 rpm, making it a lazy cruising engine that has the ability to tow relatively heavy loads.
Other Features
The Duramax LLY 6600 contains a cold-start management system for chilly days and fast-heating glow plugs, a Garrett turbocharger nozzle, an improved cylinder-head design, a positive crankcase venting system, and an exhaust gas recirculation system to streamline performance while keeping fuel economy under control.
